Carpal tunnel syndrome rehabilitation device

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention is generally related to carpal tunnel syndrome, and more particular to a rehabilitation device for relaxing the ligament in the carpal tunnel.

(b) Description of the Prior Art

Modern people suffer various pain and sore due to their immobile postures and repetitive actions in their lives, works, and exercises. Two common sources of pain and sore are the ligament adhesion resulted from the carpal tunnel syndrome and the epicondylitis (tennis elbow). These illnesses do not involve bones but are pathological changes out of the fatigue of ligaments. Their treatment is often through pain relief by drug medication and rehabilitation in parallel. However drug medication may very possibly lead to side effects, and rehabilitation takes a lengthy period of time. Conventional rehabilitation is usually through thermal patch or stretching, which is of little effect to injuries rooted deeply in the wrist such as the carpal tunnel syndrome. Therefore operation is often applied as an ultimate solution. In other words, existing rehabilitation devices, despite their abundance and variety, still lack those aiming for the healing and rehabilitation to illnesses like carpal tunnel syndrome and tennis elbow, which are so common to the modern office workers. Therefore, there is an urgent need for such rehabilitation devices.

SUMMARY OF THE INVENTION

To resolve the pain and discomfort from carpal tunnel syndrome and tennis elbow, a novel rehabilitation device is disclosed herein where, by simple swinging of the palm upward and downward, the wrist ligament is simultaneously massaged and relaxed, thereby easing the pain and discomfort of carpal tunnel syndrome. With the present invention, a user without special technique may still conduct simple and effective self-rehabilitation to the wrist and elbow.

The rehabilitation device includes upper and lower members clamping a wrist from above and below. An upper bulge element and a lower bulge element are correspondingly positioned in the middle of the inner faces of the upper and lower members, respectively, for pressing against a gap between the ulna and radius of the wrist from above and below. The upper member has two positioning elements on the inner face to the lateral sides of the upper bulge element to reliably position the rehabilitation device. A strap wraps around outer faces of the upper and lower members so as to tight the upper and lower members on the wrist from above and below. By swinging the palm up and down, the bulge elements press into the gap and provide massage and relaxation to the ligament inside.

The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

The present invention provides a rehabilitation device for relaxing the ligament in the carpal tunnel. As shown in <figref idref="DRAWINGS">FIGS. 1 to 3</figref>, the rehabilitation device includes upper member <b>10</b> and lower member <b>20</b> having crescent-shaped inner faces. The upper and lower members <b>10</b> and <b>20</b> have a length about 3 cm, and have bulge elements <b>11</b> and <b>21</b> correspondingly positioned in the middle of their inner faces, respectively. The bulging elements <b>11</b> and <b>21</b> have a height between 15 and 18 mm and a roughly oval-shaped base with a width between 10 and 15 mm and a length about 20 mm. The base's length is slightly smaller than the width of the upper and lower members <b>10</b> and <b>20</b>. The bulge elements <b>11</b> and <b>21</b> shrink gradually from their bases outward for 5 to 10 mm. The two ends of each base have widths slightly smaller than the width of the base for 5 to 8 mm, thereby forming a thin and flat cone-like shape similar to a bamboo shoot. For the upper member <b>10</b>, there are two capsule-shaped positioning elements <b>12</b> on the inner face to the lateral sides of the bulge element <b>11</b>. The positioning elements <b>12</b> is slightly lower than the bulge element <b>11</b>. When the upper member <b>10</b> is placed on a wrist of a user with the inner face facing the wrist, the bulge element <b>11</b> would be against a gap between the ulna and radius adjacent to the ligament. The two positioning elements <b>12</b>, by pressing the lateral sides of the wrist, provide positioning support and prevent the upper member <b>10</b> from displacement. The lower member <b>20</b>, besides having similar curved inner face and bulge element, has a flat bottom side. When the wrist is sandwiched between the upper and lower members <b>10</b> and <b>20</b>, the bulge element <b>21</b> of the lower member <b>20</b> presses against the gap between the ulna and radius adjacent to the ligament from below. A strap <b>22</b> is then threaded through slot openings <b>13</b> and <b>23</b> located respectively at two ends of the upper and lower members <b>10</b> and <b>20</b>. Alternatively, the slot openings <b>13</b> and <b>23</b> may be configured on ear pieces extended from the two ends of the upper and lower members <b>10</b> and <b>20</b>, respectively. The strap <b>22</b> has a fastener section <b>221</b> on one side so that the strap <b>22</b> locks to itself after forcing the upper and lower members <b>10</b> and <b>20</b> to provide a comfortable and reliable grip on the wrist. To place the strap <b>22</b> accurately on outer faces of the upper and lower members <b>10</b> and <b>20</b>, walls <b>14</b> and <b>24</b> are provides along two main edges of the outer faces of the upper and lower members <b>10</b> and <b>20</b>, respectively, so that the strap <b>22</b> does not slip outside the outer faces of the upper and lower members <b>10</b> and <b>20</b>. After the strap <b>22</b> tightly binds the upper and lower members <b>10</b> and <b>20</b> to the wrist, the bulge elements <b>11</b> and <b>21</b> clamp the gap between the ulna and radius from above and below. Then, by flipping the palm and swinging the palm up and down, the bulge elements <b>11</b> and <b>21</b> squeeze into the gap and relax the ligament. In the meantime, the upper and lower members <b>10</b> and <b>20</b> are always positioned correctly without displacement and slack. As such, the ligament within the carpal tunnel is naturally stretched and massaged. The carpal tunnel syndrome resulted from the ligament's adhesion is therefore eased and rehabilitated.

The lower member <b>20</b>, in addition to working with the upper member <b>10</b> to improve the discomfort of the carpal tunnel syndrome, may also be applied independently. The lower member <b>20</b> may has its flat bottom side rested firmly on a flat surface such as a table top. Then, as shown in <figref idref="DRAWINGS">FIG. 4</figref>, the tip of the bulge element <b>21</b> directly contacts the ligament within the olecranon fossa on the back of the elbow joint and provides adequate relaxation and massage to the elbow suffering ligament adhesion or the so-called tennis elbow. The flat bottom side of the lower member <b>20</b> provides convenient and reliable positioning without displacement while the elbow is treated, ensuring the elbow safety and operation stability.

As described above, the gist of the present invention lies in the convenient and tight wrapping of the wrist from the upper and lower members <b>10</b> and <b>20</b> through the strap <b>22</b>. Then by simple swinging of the palm upward and downward, the wrist ligament is simultaneously massaged and relaxed, thereby easing the pain and discomfort of carpal tunnel syndrome. The lower member <b>20</b> may be independently positioned on a flat surface and provides massage and rehabilitation to the elbow suffering the so-called tennis elbow. The strap <b>22</b> provides convenient tightening of various degrees. With the present invention, a user without special technique may still conduct simple and effective self-rehabilitation to the wrist and elbow.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
